SubQuery Paras NFT

This project indexes NFTs from https://paras.id/. It specifically indexes actions where the receiver is marketplace.paras.near on the buy method. In otherwords, NFTs that have been bought in the Paras marketplace.

Preparation

Environment

Typescript are required to compile project and define types.
Both SubQuery CLI and generated Project have dependencies and require Node.

Install SubQuery CLI globally on your terminal by using NPM:

npm install -g @subql/cli

Run help to see available commands and usage provide by CLI

subql help

Clone project

git clone https://github.com/seandotau/subql-paras-nft.git

query {
  nearTxEntities(filter:{
    block:{equalTo:85291528}
  }) {
    totalCount
    nodes {
      id
      block
      receiver
    }
  }
  nearActionEntities(filter:{
    block:{equalTo:85291528}
  }) {
    totalCount
    nodes {
      id
      block
      receiver
      sender
      tokenId
      nftContractId
      ftTokenId
